Compatible Font Libraries

+ +

+ There are 2 font libraries compatible with Maker.js: +

+ + +

- Maker.js uses Opentype.js by Frederik De Bleser to read TrueType and OpenType fonts. - Please visit the Opentype.js GitHub website for details on its API. + The Text model automatically detects which library you're using and handles both transparently. You will need to know how to load font files before you can use them in Maker.js.

Finally, a phenomenon to be aware of is that fonts aren't always perfect. You may encounter cases where paths within a character are self-intersecting or otherwise not forming closed geometries. This is not common, but it is something to be aware of, especially during combine operations. diff --git a/docs/fonts/twemoji/LICENSE b/docs/fonts/twemoji/LICENSE new file mode 100644 index
